what is roll mill

What is a Z-Mill? - Definition from Corrosionpedia. The Z-mill uses cascaded supporting rolls instead of using a single pair of rolls to apply force on the small work rolls in the center. The Z-mill is designed to make heavy reductions at high speeds and used to roll both ferrous and …

Milling cutter - Wikipedia

Milling cutters are cutting tools typically used in milling machines or machining centres to perform milling operations (and occasionally in other machine tools).They remove material by their movement within the machine (e.g., a ball nose mill) or directly from the cutter's …

Rolling (metalworking) - Wikipedia

Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.

Finite Element Modeling of Strip Curvature During Hot Rolling

for pass 1 and 15mm for pass 2 and this mimics the conditions found at the hot rolling mills of various finishing stand. Fig. 3.2 Definition of pass height To predict the effects of differential roll speed the upper work roll has been given a 5 % higher angular velocity. This represents the maximum limit that a rolling operator has on the ...
